Welcome to the never ending problem with this damn driver. I and many
others have had the exact same problem with this driver. It's always
blamed on hardware. Many others have reported similar problems. Your
the first to have one exactly like me. I have 2 machines doing this
same thing. If you search the archives you'll be amazed. yet nothing
will be done about it. There is another driver around. I think it's
done by adaptec. You could try it. I can't point you to it just now.
The problem for me is pretty intermittant in that it only happens
1 of 4 reboots. I've lived with it for almost a year. Like you bothe
machines I have  never do this when my Yamaha CD8424 is removed from
the bus. Once it gets by that stupid area after the inst dnld all is
ok. You won't find a solution to your problem using this driver.
Good luck...
